SHOCK-ABSORBER.

I To all whom it may concern:

Gnoner. F. Vorenr, a San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Shock-Absorbers, of which the following is a specification.

My invention relates to a' shock absorbing device adapted to be interposed between the regular leaf spring and the axle of an automobile or like road vehicle, and in which a principal oscillatory lever is pivotally supthe axle, and a second or complementing lever operating in conjunction with the former and pivotally Be it known that I,

- connected thereto, which has one end supported by a portion of the vehicle and which is approximately vertically movable. relatively to the axle and its other end resiliently yieldingly supported by said oscillatory lever and adapted to be connected 'to and supporting one end-of the said regular leaf sp g- With the foregoing and other objects and urposes in view which will appear as the escription proceeds, the invention resides in the combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being finderstood that changes in the preciseembodiment' of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings: v Figure 1 is a front-end elevation of a portion of the left-hand side of an automobile with -my shock absorber applied thereto; Fig. 2 is a vertical section of the complementing lever and its connection with the regular leaf spring; F1g.3 is a vertical section of the oscillatory lever and its supporting perch or bracket and a vertical sectional view of a fragment'of the axle; Fig. 4 is a view in a direction indicated by the arrow A, Fig. 1 of a portion of the present invention, showing also a portion of the vehicles regular leaf spring; Fig. 5 is a sectional view on line M, Fig. 1; Fig. 6 is a sectional view on line b-b, Fig. 1; and Fig. 7 is a sectional view of a portion of the invention on line cc, Fig. 1. c a

the right-hand side rear as well as to front of any vehicle.

Like numerals refer to like parts throughout the several views:

Referring to the drawings: I

designates a vehicle axle supported at one end by a wheel 2, and 3 the vehicles frame supported by a regular leaf spring 4.

To the upper' side of secure a porch or bracket 5 provided at its having transverse opensmgs 7 7 through which extends a pivot pm 9 is a resiliently flexible leaf spring lever provided at its outer end with a transverse openlng 10 for pivotally mounting it on the pin 8, and provided at a transverse opening 11 for pivotally con.- necting it to the cars 12 12 projecting upvardly from an intermediate section of a mplementing lever 13, by means of a pivot is preferably bowed gently upwardly intermediate its ends, and is disposed above the outer end section of the-spring 4 and extends in a general direction therewith.

15 is a leaf spring disposed above the oscillatory lever 9 and extends in a general direction therewith. The inner end of which being unitarily secured to the inner end of the lever. and is preferably, and as such shown in the drawings, a continuation of the axle I rigidly."

its inner end withas well-as to the left- '55 the latter doubled back upon itself after M forming the opening 11 at the inner end thereof. and is adapted to be in ing engagement therewith for a greater or less distance. The outer section of the spring 15 is bowed'upwardly from its intermediate section and disposed upwardly and apart from a registering section of the lever liently flexible loop or scroll 16 having at its free end an opening'l'l' supporting a pivot pin 18. The free end section of the spring 15 and its loop 17 being movable downwardly against the tension of said spring and loop.

For the reason that the tension of itself.

bodily bearoscillatory lever 9' intermediate its ends supports the spring 15,

The outer end of the complementing lever 13 is bifurcated forming two upwardly extending arms 19 19 disposed one on each side of the lever 9, spring 15 and its loop 16. The 5 upper or supported by the free end of the loop 16 by means of the pin 18. The inner section the complementing lever 13 is also bifurcated thereby forming two arms 20 20, adapted to straddle the leaf spring 4 from the upper side thereof, and provided at their free ends with openings 21 21 adapted to receive the lower ends 22 22 of an inverted stirrup P supported by the frame 3. If so desired, tnc stirrup 23, instead of being supported by the frame 3, may be supported in a similar manner, by the regular leaf spring 4 intermediate the ends ofthe latter.

To an outer section of the lever 13 is piv otally connected oneend of the regular lea spring l by means of pivot pins 24 and 25 and links'26 26 assembled in a well known manner.

In forming the opening 10 in the outer end of the lever 9, I bend the end of the lever downwardly thence looping it backwardly upon itself and thence inwardly and downwardly a suitable distance thereby forming a stop 27 adapted to operatively engage with a shoulder 28- on the perch when the lever is rotated downwardly a certain distance upon the pin 8, to prevent the outer end of the leaf spring from operatively contacting with the.- axle 1. v

From the foregoing description of my invention, and as it is shown by the drawings, it can be seen that the spring 15 and its loop 16, together with the lever 9, may resiliently yieldingly support one on of the regular leaf spring 4. The arms 22 22 and the shackle connection between the end of the-- spring i and the lever 18, forming intermediate means.

- Throughout the foregoing specification, and in the claims hereinafter following, to facilitate designating the relative positions of the different portions, sections and parts forming the present invention, in connection with the vehicle, the term, outer end, or, outerends, shall designate the end or ends nearest to the vehicle wheel, and the term, inner end, or, inner ends, shall designate the end or ends farthest away from the wheel.
